Parasite infracommunities of Leporinus friderici: A comparison of three tributaries of the Jurumirim Reservoir in southeastern Brazil

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT The degradation and homogenization of natural habitats is considered a major cause of biotic homogenization. Many studies have been undertaken on the effects of dams on aquatic wildlife, in particular fish assemblages. But how do dams affect the parasitic fauna of such fish? The aim of the prese...

Diameter distribution in a Brazilian tropical dry forest domain: predictions for the stand and species

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Currently, there is a lack of studies on the correct utilization of continuous distributions for dry tropical forests. Therefore, this work aims to investigate the diameter structure of a brazilian tropical dry forest and to select suitable continuous distributions by means of statistic tools fo...

N deposition affects allelopathic potential of Amaranthus retroflexus with different distribution regions

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT This study aims to determine the allelopathic potential of Amaranthus retroflexus (Ar) with different climatic zones on seed germination and growth of A. tricolor (At) treated with a gradient N addition. Ar leaf extracts only displayed significantly allelopathic potential on the underground grow...

Screening of melon genotypes for resistance to vegetable leafminer and your phenotypic correlations with colorimetry

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Melon is one of the most important vegetable crops in the world. With short cycle in a system of phased planting, phytosanitary control is compromised, and a great volume of agricultural chemicals is used to control vegetable leafminer. Genetic control is an ideal alternative to avoid the damage...

Assessment of fatigue using the Identity-Consequence Fatigue Scale in patients with lung cancer

J. bras. pneumol; 43 (3), 2017
ABSTRACT Objective: To evaluate the properties of the Identity-Consequence Fatigue Scale (ICFS) in patients with lung cancer (LC), assessing the intensity of fatigue and associated factors. Methods: This was a cross-sectional study involving LC patients, treated at a teaching hospital in Brazil, who co...

Sleep-disordered breathing in patients with COPD and mild hypoxemia: prevalence and predictive variables

J. bras. pneumol; 43 (3), 2017
ABSTRACT Objective: To infer the prevalence and variables predictive of isolated nocturnal hypoxemia and obstructive sleep apnea (OSA) in patients with COPD and mild hypoxemia. Methods: This was a cross-sectional study involving clinically stable COPD outpatients with mild hypoxemia (oxygen saturation ...

Ultrasound-guided intrapleural positioning of pleural catheters: influence on immediate lung expansion and pleurodesis in patients with recurrent malignant pleural effusion

J. bras. pneumol; 43 (3), 2017
ABSTRACT Objective: To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE). Methods: This was a retrospective study nested into a larger prospective cohort study including patien...

Emergency percutaneous nephrostomy versus emergency percutaneous nephrolithotomy in patients with sepsis associated with large uretero-pelvic junction stone impaction: a randomized controlled trial

Int. braz. j. urol; 43 (3), 2017
ABSTRACT Introduction A randomized trial was conducted prospectively to evaluate the efficacy, related complications, and convalescence of emergency percutaneous nephrolithotomy compared to percutaneous nephrostomy for decompression of the collecting system in cases of sepsis associated with large uret...

Coronary perfusion pressure during antegrade cardioplegia in on-pump CABG patients

Abstract Objective: The aim of this study was to investigate whether aortic tension estimated by palpation and cardioplegia infusion line pressure provide results equivalent to those obtained with direct aortic intraluminal pressure measurement. Methods: Sixty consecutive patients who underwent coronar...

Cardiopulmonary resuscitation in an average brazilian intensive care unit: should we perform less or better?

Abstract Introduction: Few data can be found about cardiac arrest in the intensive care unit outside reference centers in third world countries. Objective: To study epidemiology and prognostic factors associated with cardiac arrest in the intensive care unit (ICU) in an average Brazilian center. Metho...
