During surveys conducted on Neotropical , a new endemic species was found in the Brazilian campos rupestres of the Espinhaço Range. Here, this new remarkable species, namely Pansarin & E.L.F. Menezes, is described and illustrated. A phylogeny for is presented and the relationships between Neotropical species are discussed. The position of among Neotropical is discussed within an evolutionary context. is recognized by its rupicolous habit, its reptant stems, and its sessile and rounded leaves. This remarkable new taxon emerges in a clade that includes Rolfe and Rolfe. Vegetative and floral features support a close relationship between and sister taxa, mainly regarding the apical inflorescence (), the type of appendages of the central crest of the labellum, and the labellar color pattern. Phylogenetic inference suggests that the circumscription of Neotropical groups needs revision.

Introduction: Post-stroke cognitive impairment (PSCI) and dementia affect short- and long-term outcome after stroke and can persist even after recover from a physical handicap. The process underlying PSCI is not yet fully understood. Transcranial Doppler ultrasound (TCD) is a feasible method to investigate cerebrovascular aging or dementia, through the pulsatility index (PI), the cerebrovascular reactivity (e.

Purpose: To develop an artificial intelligence (AI) algorithm for automated measurements of spinopelvic parameters on lateral radiographs and compare its performance to multiple experienced radiologists and surgeons.
Methods: On lateral full-spine radiographs of 295 consecutive patients, a two-staged region-based convolutional neural network (R-CNN) was trained to detect anatomical landmarks and calculate thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), and sagittal vertical axis (SVA). Performance was evaluated on 65 radiographs not used for training, which were measured independently by 6 readers (3 radiologists, 3 surgeons), and the median per measurement was set as the reference standard.

Postinfarction ventricular septal rupture (PIVSR) is a rare but serious complication of acute myocardial infarction. Determining how to conduct surgical repair safely is critical. We compared the outcomes of Impella and intra-aortic balloon pump (IABP) implantation during perioperative mechanical circulatory support management in patients with PIVSR (n = 22).

Background: System calibration is essential for accurate SPECT/CT dosimetry. However, count losses due to dead time and pulse pileup may cause calibration errors, in particular for I, where high count rates may be encountered. Calibration at low count rates should also be avoided to minimise detrimental effects from e.

Purpose: Recent research suggests that caffeine use may promote a range of adjustment difficulties among adolescents, particularly during the middle school years. The effects of caffeine are particularly concerning given the increased use of high-dosage caffeine products, such as energy drinks, among youth. We investigated the influence of caffeine use on trajectories of conduct problems among early adolescents.
