Contrasting responses of above- and belowground diversity to multiple components of land-use intensity.

Land-use intensification is a major driver of biodiversity loss. However, understanding how different components of land use drive biodiversity loss requires the investigation of multiple trophic levels across spatial scales. Using data from 150 agricultural grasslands in central Europe, we assess the influence of multiple components of local- and landscape-level land use on more than 4,000 above- and belowground taxa, spanning 20 trophic groups.

Intensive land use drives small-scale homogenization of plant- and leafhopper communities and promotes generalists.

The current biodiversity decline through anthropogenic land-use not only involves local species losses, but also homogenization of communities, with a few generalist species benefitting most from human activities. Most studies assessed community heterogeneity (β-diversity) on larger scales by comparing different sites, but little is known about impacts on β-diversity within each site, which is relevant for understanding variation in the level of α-diversity, the small-scale distribution of species and associated habitat heterogeneity. To obtain our dataset with 36,899 individuals out of 117 different plant- and leafhopper (Auchenorrhyncha) species, we sampled communities of 140 managed grassland sites across Germany by quantitative vacuum suction of five 1 m plots on each site.

Safe prone checklist: construction and implementation of a tool for performing the prone maneuver.

Objective: To construct and implement an instrument (checklist) to improve safety when performing the prone maneuver.

Methods: This was an applied, qualitative and descriptive study. The instrument was developed based on a broad review of the literature pertaining to the construction of a care protocol using the main electronic databases (MEDLINE, LILACS and Cochrane).

Good practices for prone positioning at the bedside: Construction of a care protocol.

Last year, interest in prone positioning to treat acute respiratory distress syndrome (ARDS) resurfaced with the demonstration of a reduction in mortality by a large randomized clinical trial. Reports in the literature suggest that the incidence of adverse events is significantly reduced with a team trained and experienced in the process. The objective of this review is to revisit the current evidence in the literature, discuss and propose the construction of a protocol of care for these patients.

IMP3 expression in serous tumors of the ovary.

Insulin-like growth factor II mRNA-binding protein (IMP3) is an oncofetal protein involved in embryogenesis, which is expressed in a variety of malignant neoplasms. It is rarely expressed in normal adult tissue and benign tumors. The aim of this study was to evaluate the expression of IMP3 in benign and malignant serous tumors of the ovary.

Chronic lymphocytic leukemia/small lymphocytic lymphoma involving the aortic valve.

Chronic lymphocytic leukemia/small lymphocytic lymphoma is a neoplasm composed of monomorphic small B lymphocytes in the peripheral blood, bone marrow, spleen, and lymph nodes, forming proliferation centers in tissue infiltrates (Muller-Hermelink HK, Montserrat E, Catovsky D, et al. Chronic lymphocytic leukaemia/small lymphocytic lymphoma, in Swerdlow SH (ed). WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues.

Oncocytoma of the adrenal gland medulla.

We report an unprecedented case of an oncocytoma of the adrenal gland medulla in a 61-year-old woman. The patient presented with right flank pain and hematuria. Computed tomographic studies revealed a right adrenal gland mass that measured 2 cm, which was subsequently excised laparoscopically.

Vigabatrin in refractory childhood epilepsy. The Brazilian Multicenter Study.

Children, 47, with various types of severe drug-resistant epilepsy were entered into a prospective, add-on, open trial with vigabatrin. Patients with West syndrome and idiopathic generalized epilepsies were excluded. Seven children had the drug withdrawn, five because of increase in seizure frequency and two because of adverse effects.

[Comparison between the EEG of natural sleep and the induced by chloral hydrate in relation to paroxysmal changes and baseline rythm].

EEG changes associated with the use of chloral hydrate (50 mg/Kg) to induce sleep were evaluated in 50 epileptic children (ages 1 to 12 years), either taking no anticonvulsants or on monotherapy. It was observed that chloral hydrate was capable of inducing sleep without side effects and was capable of modifying the sleep EEG, improving organization of sleep spindles and generalized paroxysms.
