New morphological and biological contributions to adults and immature forms of (Fulgoromorpha, Delphacidae) in wetlands of Argentina.

In the search for insects as biological control agents for the water primrose, the delphacid (Delphacidae) was found on Ludwigiagrandiflorasubsp.hexapetala (Onagraceae) in a wetland of Central East Argentina. The morphology of the unknown females (brachypterous and macropterous) and immature stages are described and illustrated.

The educational community and its knowledge and perceptions of native and invasive alien species.

Environmental education seeks to foster an appreciation for nature and the impact of humans on it while introducing citizens to scientific thinking. Biological invasions affect different aspects of life on earth and mandate urgent management actions. Education and public awareness are strongly recommended for successful prevention and management of invasive alien species (IAS).

Prediabetes is a risk factor for cardiovascular disease following renal transplantation.

Prediabetes and post-transplant diabetes mellitus affect about 20-30% of renal transplant patients. The latter is a risk factor for cardiovascular disease. However, no clear evidence linking prediabetes and cardiovascular disease is available.

EEG findings and outcomes of continuous video-EEG monitoring started prior to initiation of seizure treatment in the perinatal stroke.

Background: To analyze the findings in the background EEG activity of infants who suffered perinatal stroke.

Methods: Eleven neonates born 2009-2014 diagnosed of ischemic stroke by MRI (three of them with multistroke) underwent continuous video-EEG monitoring. Visual and spectral (power spectrum and coherence) analyses of the background EEG was performed in three moments: 1) Onset of EEG recording (prior to initiate seizure treatment), 2) Post-ictal epoch (1-2 h after the last seizure), and 3) one-two days after seizure control.

Visual and Quantitative Electroencephalographic Analysis in Healthy Term Neonates Within the First Six Hours and the Third Day of Life.

Background: What constitutes a "normal" background electroencephalography (EEG) rhythm immediately after birth is not well understood. We performed video-electroencephalography recordings in the first six hours (first measure) and the third day of life (second measure) for evidence of transient changes in brain function.

Methods: We performed a cohort study of an incidental sample of healthy term neonates in a single-center nursery.

Comparison of endoscopic ultrasonography-guided fine-needle aspiration cytology results with and without the stylet in 3364 cases.

Background And Aim: Endoscopic ultrasound-guided fine-needle aspiration cytology (EUS-FNA) is traditionally carried out with the stylet, as it is believed to prevent blockage or contamination of the needle by tissue coming from the gastrointestinal wall. However, this recommendation has not been demonstrated on an empirical basis. The aim of the present study was to compare the yield of EUS-FNA in a very large series of patients with (S+) and without (S-) the stylet.

Phenrica littoralis (Bechyné, 1955) (Coleoptera: Chrysomelidae) a potential candidate for the biological control of alligator weed, Alternantheraphiloxeroides (Martius) Grisebach (Amaranthaceae): redescription of the adult, first description of immature stages, and biological notes.

Flea beetles of alligator weed, Alternanthera philoxeroides (Martius) Grisebach (Amaranthaceae), were collected in Argentina, Uruguay, Paraguay, and Brazil. Species in the genera Disonycha Chevrolat, Agasicles Jacoby, Systena Chevrolat and Phenrica Bechyné were frequently found on this weed. Phenrica littoralis (Bechyn6) was the most abundant within this genus.

Incidence and predictors of postpolypectomy bleeding in colorectal polyps larger than 10 mm.

Background: It is well-established that the risk of postpolypectomy bleeding (PPB) increases with polyp size, but little is known about the factors that predict PPB in polyps larger than 10 mm.

Aim: The aim of this study is to assess the incidence and risk factors for PPB in colorectal polyps larger than 10 mm.

Methods: A historical cohort study was carried out in an open access endoscopy unit from January 2007 to December 2008.

Reproducibility measuring the angle of proximal junctional kyphosis using the first or the second vertebra above the upper instrumented vertebrae in patients surgically treated for scoliosis.

Study Design: A historical cohort study.

Objective: To evaluate the reproducibility of this measure in proximal junctional kyphosis (PJK) and to determine whether differences exist between first and second vertebrae angles.

Summary Of Background Data: There are no previous studies on the precision and accuracy of selecting the first or the second vertebra above the upper instrumented vertebrae to determine the degree of spinal angulation after surgery.
